OIL-ATOMIZER.

rift J To all whom'it may concern:

Be it known that we, WHrLLDIN and EU- GENE O. FOSTER, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Imrovements in Oil-Atomizers, of which the ollowing is a full, clear, and exact description.

Our invention relates to an apparatus for atomizing oil, and pertains particularly to the injection and'atomizing of oil in a gas producer for the purpose of making illuminating or other gas;

The principal object of the invention is to provide a combined oil injector and atom- 1zer which is capable of conpletely breaking up or atomizing oil of all grades and characters.

' A further object of the invention is to provide a simple structv'. in which the oil, and

.he various atomizin steam jets, are independently adjustabh and in which only a iinimum body of on is exposed to the heat" of the furnace priorto'its atomization.

With these and ot ie octs in view our Y invention consists in the construction, com

bination, in the location and in the arrange re-combine as a ment of parts, as hereinafter set forth and shown. and finai. particularly-"pointed out in the appended claims.

A highly heated chamber is ordinarily used into which the oil and steam are injected, and where they are disassociated, and reduced to their component elements by the heat of the chamber, and the fire brick.

gas, plays an important Patented Dec. 3, 1907...

In orderto have this process successful it is important that the 01 is very finely atomized and mixed with steam before it is subjected to the heat, since otherwise the oil tilled away, leaving a tarry residue which could not be atomized, or made into a gas. In practice, the oil must be broken up into particles so exceedingly minute that they are completely reduced and disassociated into their component elements almost immediately up on reaching the heat zone of the furnace chamber in which the process takes place. In carrying out our resent invention we aim to secure this resu t.'

Referring to the drawings and to the various views in which like parts are designated by the same reference sign, 1 denotes the casing, preferably cylindricalin form, and screw threaded at 2, so as to be receivedinto the wall of a furnacechamber, or in. any des7 l elation. The casing 1 is made hollow, its inside surface or wall-3 is preferably :--rnooth and straight throughout the whole or art of its length so as to constitute a uide for certain. movable parts or members ereinafter described. We prefer to make .he nterior surface 3 of circular section, as

this form is most convenient to manufacture. I

Within 'he casing 1 are contained a pair of movable tarts 4' and 5, of which 5 consti tutes what I shall tenn the steam delivery chamber, while the part constitutes the oil delivery chamber. These parts are both conveniently made of semi-cylindrical form, as shown in Figs. 5 and 7, so that when they are assembled together they will be closely received and guided by the surface 3 of the would have its more volatile products dis-- NSXLVANIA, ASSIGNORS' casing 1. 6 denote tenons or uides adapted 4 to be slidably received in t e grooves or m rtises 7, of the other member.

The oil delivery chamber 4 is drilled or apertured throughout its length with a conical or tapering hole 8, and a correspondingly coned or tapering plug 9 is arranged to be closely received within the tapered hole 8.

The arrangement is sue that when the plug 9 is in its right hand or withdrawn relation, a space is left through which the oil may flow and issue through the various ducts 11. When the plug 9 is moved to the left, the space is entirely closed up 5 and no oil can flow through the ducts 11, nor {)emain in any part of the oil delivery cham- For the purpose of moving the plug 9 we arrange a handle 14 upon the rod 10, which 0 runs through a stufi'ing box or gland 15, on a pipe 16, forming a eontin'uation of the oil delivery chamber 4.

- 17 indicates a branch connection leading to any source of oil supply (not shown).

The steam delivery chamber is longitudinally drilled or apertured, as shown at 18, and is provided with a number of nozzles 19, issuing through the lat face 20 of the steam delivery chamber. The arrangement of the 20 various nozzles 19 is such that they deliver against the rifiles 13 previously mentioned,

and the jets are deflected thereby, so that the steam current flows tangentially past the various oil ducts 11. The oil delivery chamber and the steam delivery chamber are capable of being adjusted with relation to one another so that the relation of the steam jets to the oil duets can be varied. For this purpose the steam delivery chamber has an extension 21 thereon, the end of which is concaved to iit into a groove 22, of a nut 23, which moves on the threaded stud 24, projecting from the oil delivery chamber. By turning the nut, the

two chambers are moved in and out relatively to one another.

In addition to the steam passage 13, we provide additional passages for superheated or other steam or gas in both the oil and the steam delivery chambers. These passages are indicated in dotted lines at 25 and 25 respectively, and terminate in transverse cavities 26 and 26, having delivery nozzles 27, and 27. These nozzles issue on bevel portions 28 of the respective chambers by which the steam jets impinge against the stream of mixed. oil and steam coming from the ducts 11 and nozzles 19. This stream normally passes outward in a flat sheet from between the ends of the chambers 4 and 5.

The use and operation will be readily understood from the preceding description. The handle 14 is adjusted so that a space is left between the plug 9 and its conical hole 8,

through which oil flows and issues through the ducts 11. The steam jets from the nozzles 19 aspirate the oil from the ducts 11, and the combined current issues in a flat stream from between the ends of the chainhere as above stated. At this point the made suitable to the requirements of the gasifying process. It'will be seen that the oil flow is minutely controllable by the handle .14, and the steam flow is, of course, regulated by throttling the steam supply to the various steam passages.

In Figs. 8 to 11 inclusive, We have illustrated a slightly different form of construction in which not only are the at'omizing steam jets adjustable with relation to the oilducts, but the additional steam jets, which finally complete the atomizing process, are also adjustable with relation to the others. For this purpose we make use of three chambers. 30 is the oil delivery chamber, having an oil cavity 31, and oil delivery ducts 32 leading therefrom. 33 is the initial steam delivery chamber, having a cavity 34, and steam nozzles 35, which are inclined so as to deliver a stream in a partly tangential direction over the oil ducts 32. Referring to Figs. 10 and 11, it will be seen that the end of the chamber 30 is recessed or chamfered at 36. The member 33 has a ledge or protuberance 37 thereon, which fits the chamfered portion 36 of the opposed member. hen the members are assembled, a diagonal gap or opening 38 is produced, the width of which can be regulated by varying the relation of the two chambers. 39 denotes the secondary steam delivery chamber which has a cavity 40, and a delivery opening 41, inclined with respect thereto, and with res set to the opening 38 above mentioned. 0th of the steam delivery chambers 33 and 39 are adjustable with respect to the oil delivery chamber 30 by any means, as for example, by grooved screws 42 cooperating with a yoke 43, fixed to the member30. The various chambers 30, 33 and 39 have threaded inlets 44,45 and 46, by which any flexible or convenient pipe connections are made to suitable sources of supply. The 0 oration of this form of my invention will 6 sulliciently obvious without detailed description. The oil issues from the ducts 32 and is carried away by the steam ets from the nozzles 35. As the combined stream of steam and oil issues from the opening 38, it is impinged against and completely atomized and broken up by the jet of steam from the opening 41. The various chambers are adjusted so as to get the best effects.

An important feature of the invention lies in the arrangement by whichianyidripping away or loss of the oil is completely prevented. It will be observed that in both forms of construction a drip tray is formed iniwhich any surplus drops of oil are caught iand immediately afterward atomized bythe steam jets. In the structure of Figs. 1 to 7 inclusive the scallops or riffles w zard-depressedslightly below the plane of the surrounding edge. Any surplus oil is thereby prevented from escape and is exposed to the steam 1330 blast in the same way as the oil in the ducts. In the form of the invention shown in Figs. 8 to 11 inclusive the oil from the ducts 32 may drip into the depressed face of the steam chamber where it is of course immediately exposed to the steam blast. In both cases it is essential that the atomizer be horizontally disposed to get the best effects.
